[0002] Polyester resin is a general term for high molecular weight compounds formed by the condensation polymerization of diols, diacids, or polyols and polyacids. Polyester resin is an unsaturated polyester adhesive, which is mainly processed from unsaturated polyester resin, initiator, accelerator, filler and other raw materials. Nowadays, the processing of polyester resin is mainly carried out in a stirred tank for mixing and reaction.

[0003] In the prior art, such as Chinese Patent No. CN217910437U, there is a stirring device for polyester resin production reaction, including a mixing chamber and a connecting frame.

A motor is installed at the upper end of the connecting frame, and a stirring rod is fixedly connected to the output end of the motor. A stirring blade is fixedly connected to the outer wall of the stirring rod, and the stirring rod and stirring blade rotate horizontally. This stirring device for polyester resin production reaction has a simple structure, is easy to operate, facilitates shock absorption and impact buffering, has a heat preservation effect, facilitates uniform mixing, facilitates control of the discharge speed, prevents accumulation and leakage from affecting the discharge efficiency, and increases the practicality of the device.

[0004] While the above-mentioned solution has the advantages mentioned above, it also has the following disadvantages: Although it can be operated by starting a motor, with a stirring rod installed at the motor's output end, causing the stirring rod to rotate horizontally and the stirring blades around it to rotate accordingly, and the stirring blades are arranged in a spiral shape so that the polyester resin material to be stirred rotates to the bottom and then rises back to the top, achieving the effect of uniform mixing and avoiding clumping, the polyester resin has a certain degree of viscosity, which makes it easy for the polyester resin to stick to the insulation layer inside the mixing chamber during the mixing process, resulting in a poor mixing and reaction effect of the polyester resin. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that, although it can be operated by starting a motor, with a stirring rod installed at the output end of the motor, so that the stirring rod rotates horizontally and the stirring blades on its periphery rotate accordingly, and the stirring blades are arranged in a spiral shape so that the polyester resin material to be stirred rotates to the bottom and then rises back to the top, achieving the effect of uniform stirring and avoiding clumping, the polyester resin has a certain degree of viscosity, so during the stirring process, the polyester resin is easy to stick to the insulation layer inside the mixing chamber, resulting in poor stirring and mixing reaction of the polyester resin.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature-controlled stirring reaction device for polyester resin production, comprising: a stirring tank, and further comprising: A rotating rod is rotatably connected to the opposite side of the inner wall of the mixing tank. A stirring blade is spirally fixed to the outer surface of the rotating rod. Two scraper blades are symmetrically fixed to one end of the rotating rod. A scraper blade is fixed to the top of the scraper blades. A bracket is fixed to the top of the mixing tank. A motor is fixed to the top of the bracket. The output end of the motor is fixedly connected to the other end of the rotating rod. A heating tank is provided inside the mixing tank. Multiple heating wires are fixedly connected in a circumferential array on the opposite side of the inner wall of the heating tank. A guide assembly and a reverse stirring assembly are provided on the inner wall of the mixing tank.

[0007] Preferably, the guiding assembly includes a guide ring, the outer surface of which is fixedly connected to the inner wall of the mixing tank near the top, and two arc-shaped sliders are symmetrically slidably connected to the inner wall of the guide ring, the arc-shaped sliders being fixedly connected to the scraper.

[0008] Preferably, the outer surfaces of the two scraper blades are symmetrically rotatably connected to the inside of the mixing tank, and the outer surfaces of the two scraper blades are symmetrically rotatably connected to the inside of the mixing tank.

[0009] Preferably, the reverse stirring assembly includes multiple rotating rods 2, the outer surfaces of the multiple rotating rods 2 are rotatably connected to the top of the inner wall of the stirring tank in a circumferential array, stirring blades 2 are spirally fixedly connected to the outer surface of the rotating rods 2, gears 2 are fixedly connected to one end of the rotating rods 2, gears 1 are fixedly connected to the outer surface of the rotating rods 1 near the support, and gears 1 mesh with multiple gears 2.

[0010] Preferably, a temperature sensor is fixedly connected to the outer surface of the rotating rod near the center, and a temperature sensor is fixedly connected to the scraper on one side near the center.

[0013] Preferably, an insulation sleeve is fixedly connected to the outer surface of the mixing tank, and multiple support feet are fixedly connected to the bottom of the mixing tank in a circumferential array.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention utilizes a rotating rod to rotate scraper one and scraper two. Scraper one scrapes the raw material at the bottom of the mixing tank to prevent sticking, while scraper two scrapes the raw material adhering to the inner wall of the mixing tank to prevent sticking. Simultaneously, the rotation of scraper two drives an arc-shaped slider to rotate along the inside of a guide ring, limiting and guiding scraper two and increasing its stability. At the same time, a controller controls a heating wire to raise the temperature of the inner wall of the heating tank, transferring heat to the polyester resin inside the mixing tank. This increased temperature reduces the viscosity of the polyester resin, preventing it from sticking to the inner wall of the mixing tank and improving the mixing reaction efficiency.

[0015] This invention uses a controller to start a motor, causing its output shaft to rotate a rotating rod and a stirring blade. The stirring blade conveys the raw material from the bottom of the mixing tank upwards. Simultaneously, the rotation of the rotating rod drives a gear to rotate. Then, under the meshing action of gears one and two, gear two drives the rotating rod and stirring blade two to rotate in the opposite direction. The reverse rotation of the stirring blade conveys the raw material from the top of the mixing tank downwards. This not only prevents the raw material from accumulating at the bottom of the mixing tank but also accelerates the mixing speed, thereby reducing the overall mixing time and improving the efficiency of polyester resin production.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figure 1-4 As shown, this utility model provides a temperature-controlled stirring reaction device for polyester resin production, including: a stirring tank 1, and further including: a rotating rod 206, rotatably connected to the opposite side of the inner wall of the stirring tank 1, a stirring blade 207 spirally fixedly connected to the outer surface of the rotating rod 206, two scrapers 3 symmetrically fixedly connected to one end of the rotating rod 206, a scraper 301 fixedly connected to the top of the scraper 3, a bracket 2 fixedly connected to the top of the stirring tank 1, a motor 201 fixedly connected to the top of the bracket 2, the output end of the motor 201 fixedly connected to the other end of the rotating rod 206, a heating tank 106 is provided inside the stirring tank 1, and multiple heating wires 107 are fixedly connected in a circumferential array on the opposite side of the inner wall of the heating tank 106, and a guide assembly and a reverse stirring assembly are provided on the inner wall of the stirring tank 1.

[0021] Furthermore, such as Figure 1-4 As shown, the guide assembly includes a guide ring 302. The outer surface of the guide ring 302 is fixedly connected to the inner wall of the mixing tank 1 near the top. Two arc-shaped sliders 303 are symmetrically slidably connected to the inner wall of the guide ring 302. The arc-shaped sliders 303 are fixedly connected to the scraper 301. By rotating the scraper 301, the arc-shaped sliders 303 can be driven to rotate along the inside of the guide ring 302, which plays a limiting and guiding role for the scraper 301 and increases the stability of the scraper 301.

[0022] Furthermore, such as Figure 1-4As shown, the outer surfaces of two scraper blades 3 are symmetrically rotated and connected to the inside of the mixing tank 1, and the outer surfaces of two scraper blades 301 are symmetrically rotated and connected to the inside of the mixing tank 1. By rotating the scraper blades 3, the raw materials at the bottom of the mixing tank 1 can be scraped to prevent them from sticking. By rotating the scraper blades 301, the raw materials stuck to the inner wall of the mixing tank 1 can be scraped to prevent them from sticking.

[0023] Furthermore, such as Figure 1-4 As shown, the reverse stirring assembly includes multiple rotating rods 203. The outer surfaces of the multiple rotating rods 203 are arranged in a circumferential array and rotatably connected to the top of the inner wall of the stirring tank 1. The outer surfaces of the rotating rods 203 are spirally fixedly connected to stirring blades 205. One end of the rotating rods 203 is fixedly connected to a gear 204. The outer surface of the rotating rod 206 near the support 2 is fixedly connected to a gear 202. The gear 202 meshes with the multiple gears 204. The rotation of the rotating rod 206 can drive the gear 202 to rotate. Then, under the action of the meshing of the gear 202 and the gear 204, the gear 204 can drive the rotating rods 203 and the stirring blades 205 to rotate in the opposite direction. The reverse rotation of the stirring blades 205 conveys the raw materials above the stirring tank 1 downwards.

[0024] Furthermore, such as Figure 1-4 As shown, a temperature sensor 208 is fixedly connected to the outer surface of the rotating rod 206 near the center, and a temperature sensor 304 is fixedly connected to one side of the scraper 301 near the center. The temperature sensor 304 facilitates the detection of the temperature of the polyester resin near the inner wall of the mixing tank 1, and the temperature sensor 208 facilitates the detection of the temperature of the polyester resin at the center position.

[0025] Furthermore, such as Figure 1-4 As shown, a feed pipe 103 is fixedly connected to the top of the mixing tank 1. The feed pipe 103 is connected to the mixing tank 1, and the raw materials for producing polyester resin are added into the mixing tank 1 through the feed pipe 103.

[0026] Furthermore, such as Figure 1-4 As shown, a discharge pipe 104 is fixedly connected to the bottom of the mixing tank 1. The discharge pipe 104 is connected to the mixing tank 1. A valve 105 is fixedly connected to the outer surface of the discharge pipe 104. By opening the valve 105, the polyester resin inside the mixing tank 1 can be discharged through the discharge pipe 104.

[0027] Furthermore, such as Figure 1-4 As shown, an insulation sleeve 102 is fixedly connected to the outer surface of the mixing tank 1, and multiple support feet 101 are fixedly connected to the bottom of the mixing tank 1 in a circumferential array. The insulation sleeve 102 provides a certain insulation effect, and the support feet 101 provide a certain support effect.

[0028] Working Principle: During operation, raw materials for producing polyester resin are added to the mixing tank 1 through the feed pipe 103. The controller then starts the motor 201, causing its output shaft to drive the rotating rod 206 and stirring blade 207 to rotate. The stirring blade 207 conveys the raw material from the bottom of the mixing tank 1 upwards. Simultaneously, the rotation of the rotating rod 206 drives the gear 202 to rotate. Then, under the meshing action of gear 202 and gear 204, gear 204 drives the rotating rod 203 and stirring blade 205 to rotate in the opposite direction. The reverse rotation of the stirring blade 205 conveys the raw material from the top of the mixing tank 1 downwards. This not only prevents the raw material from accumulating at the bottom of the mixing tank 1 but also accelerates the mixing speed, thereby reducing the overall mixing time and improving the efficiency of polyester resin production. Simultaneously, the rotation of the rotating rod 206 drives the scraper 3 and scraper 301 to rotate. The rotation of scraper 3 scrapes the raw material at the bottom of the mixing tank 1. To prevent sticking, the rotation of scraper 2 301 scrapes away the raw material adhering to the inner wall of the mixing tank 1, preventing sticking. Simultaneously, the rotation of scraper 2 301 drives the arc-shaped slider 303 to rotate along the inside of the guide ring 302, which limits and guides scraper 2 301, increasing its stability. At the same time, the controller controls the heating wire 107 to heat, raising the temperature of the inner wall of the heating tank 106 and transferring the heat to the polyester resin inside the mixing tank 1. By raising the temperature of the polyester resin, its viscosity is reduced, thus preventing it from sticking to the inner wall of the mixing tank 1 and improving the mixing reaction effect. The setting of temperature sensor 2 304 facilitates the detection of the temperature of the polyester resin near the inner wall of the mixing tank 1, and the setting of temperature sensor 1 208 facilitates the detection of the temperature of the polyester resin at the center position, thereby detecting the overall temperature of the polyester resin and facilitating the temperature control of the polyester resin reaction.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
